Specification of Letters Patent.

Patented July 31, 191 *7.

Application filed October 17, 1912. Serial No. 726,225.

To all whom it may concern:

Be it known that I, FRANZ SoHoHAUs, a citizen of the German Empire, and a resldent of La Paz, Bolivia, have invented certain new and useful-Improvements in Non- Telescoping Railway Rolling Stock, of which the following is a specification.

The present invention relates to railway rolling stock and more particularly to nontelescoping railway. cars or other vehicles. Its purpose is to prevent danger to lifeand limb of passengers in case of train collisions.

While a number of devices of this general character are inexistence, it is thought to be broadly new to provide a non-telescoping railway'car, comprising a car body, pivoted on a vertical axis whereby the force of the collision, rotates the car body on this pivot so as to remove the car from the danger zone.

The invention, in a general way, comprises an ordinary truck platform restlng upon a pair of auxiliary platform sections, to which the trucks are secured. The main platform is provided with a central bearing to receive a tubular pivot connected to the car body. The car body is located on the main platform and provided with two strong crank pins, which pass through s1utable guide slots in the platform and engage the inner ends of the auxiliary platform sections. In case pressure is exerted against the outer ends of the auxiliary platform sections, the. inner ends are brought nearer together, the crank pins are acted upon to rotate the car body on its pivot and the car body becomes displaced in a plane parallel to the plane of the platform truck and at an angle to its longitudinal axis.

For the purpose of normally resisting slight pressures such as might be caused by arranging the cars and making up the trams in the railroad yards or by starting and stopping the trains and normally forcing apart the auxiliary platform, a series of resilient members are arranged between the inner ends of the auxiliary platform sections in such a way that a normal pressure against the outer ends of the sections is taken up by these springs, without displacing the car bodies.

An important feature of the invention consists in the arrangement of a valve, operated by the displacement of the platform sections and admitting air to the air brake system of the entire train, so that in case of a collision and a displacement of the car bodies, all the brakes of the entire train will be set and the train forced to stop.

The drawings illustrate the present .invention in- Figure 1, is a perspective view of the two cars, displaced after a collision,

upon which the car body rests and Fig. 6, a plan view of the under side of the sections of the auxiliary platform to which the trucks are connected, with certain parts omitted.

The car body 1, is of the ordinary construction of a passenger, Pullman or other car, or of a box or freight car, and is provided with a tubular pivot 2, located approximately at the intersection of the longitudinal and transversal axis of the car, said pivot 2 being provided with a collar 2 secured thereto for holding the same in position. Two strong crank pins 3, are secured to the bottom of the car body, fora purpose hereinafter to be particularly described. The car body may have rectangular ends or, if desired, the ends may be bevel edged. The car body rests upon the main platform 4 which is provided with two semi-circular slots or guideways 5', through which the crank pins 3 ass and are capable of sliding therein. he platform 4 is formed with two longitudinal flanges or guides 6, and with an opening 7, forming a bearing for the tubular pivot 2, of the car body. The ends of the platform 4 may also be rectangular or beveled, according to the construction of the car body.

Fig. 6 illustrates the sections 8 and 9 of the auxiliary platform which are constructed toslide along the guides or flanges 6 of the main platform 4. Formed integral with, or formed separately and secured to, each of the flanges 6, is a longitudinally extending plate 6, which plates act as guides for the sections 8 and 9 at each side thereof. The sections are arranged in one plane and below the platform 4, and suitably spaced apart and extend over the ends of the plat form 4. The inner ends of the sections 8 and 9, are provided with the oppositely projecting bearings 10 and 11, for the crank pins 3, of the car body. Truck pivots 12 and 13, are provided about midway of the sections, and lugs 14 and 15 are arranged to limit the rotation of the trucks 16 and 17, upon which the sections 8 and 9, as well as the entire car structure, are supported.

Fig. 2 represents a bottom view of the invention, showing a cross bar 18, secured to a flange 18 extending below from the section 8, which bar forms the support for a number of rods 19, rigidly secured to this bar 18 which, in turn, is fastened to the flange 18 by means of suitable rivets. Each rod 19 is provided with a helical spring 20, and these springs are held under compression by means of a rod supporting bar 21, placed upon the free ends of the rods 19 and slidable thereon. The bars 21 are held apart by a pair of separating members 22, which are located in the guides 6 of the platform 41.

A valve adapted to admit atmospheric pressure to the brake mechanism of the entire train, comprises two tubular members 23 and 24, one of which is secured to one of the bars 18 and the other to one of the bars 21. The tube 23 is provided with an opening 25 and the tube 24: with a similar opening not shown in the drawing, which are arranged to coincide on the displacements of one tube within the other and to admit air to the tube 24 and its connections, as hereinafter will more fully appear. The end of the platform sections 8 and 9, are provided with the usual buffers 26 and 27, under the pressure of the helical springs 28 and 29.

The principle of the invention is to be found in the operation of the sections 8 and 9, in connection with the crank pins 3 of the car body 1. If the sections are displaced and brought together in the longitudinal axi of a car, they cause a rotation of the crank pins 3, which glide in the guideways 5 of the platform a, and swing the car body 1, on the pivot 2, into the position indicated in 'Fig. 1 of the drawing. This operation is normally resisted by the pressure of the springs 20 and becomes effective only, when the pressure exerted upon the sections is greatly in excess of the resistance of the springs 20.

The operation of this invention consists in causing a pressure of great force in the di rection of the longitudinal axis of a train of cars such as may happen in a collision of two trains. This pressure, if only slight, will be taken up by the buffer springs 28 and 29, and have no effect whatsoever. Should this pressure, however, be greatly in excess of the force of the bufier springs, and also in excess of the force of the springs 20, then the sections 8 and 9 are forced together, and the crank pins 3, cause the swinging out of the car body, off the longitudinal axis of the train, so as to prevent any danger to life and limb of the passengers that may result from the telescoping of the cars.

The opening in the tubular pivot 2 is arranged to receive all usual pipe or other connections, for supplying the car with heat, light or compressed air and also such other piping as may be necessary to control the air brake or other devices necessary for the security of a train. It will be noted that a displacement of the platform sections, which results in the compression of the springs 20, causes the tube 24 to which the hose or pipe of the air brake is connected, to be pushed into the tube 23, until the opening 25 coincides with the proper opening of the tube 24, whereby air is admitted to the Pipe system and the air brake brought into operation to stop the entire train.
